Positions are messed up. UTG is 1st to act preflop, no?

Otherwise, fold flop. P1 is likely to have an Ace.

- If villain is indeed the 19/4 he's not TAG.
- Why are you raising on the flop, and why the minimum?
- If you have reason to assume you are ahead on the flop and turn you should call his river bet anytime, as the 2h changes nothing.
